Study on the Relationship Between Ink Drop Size and Dot Cover Area of Inkjet Plate Making

Ink drop size is an important indicator of the quality of inkjet stencil, which directly affects the accuracy of the printing dot cover area and the stability of the inkjet stencil. According to the nozzle print control principle, this paper has designed the test file, realized the measurement of microcosmic ink droplet shape by using edge detection, contour extraction, and other image processing technology and studied the relationship between the microdroplet size and the printing dot cover area. Through the methods, this paper realizes the rapid detection of ink drop size.
